EVA

[Ramona]

Is it required that a farm standing stallions inform breeder's if a stallion is an EVA Shedder?

[foothillsequine]

It would be prudent if nothing else. Are you going to be standing one of the Oakhurst studs? If so, which one? Many of them were EVA shedders....

Jack had a blurb on their website regarding EVA, you should look at it.

YIKES!!!!! If I sent a mare to a stallion, and the farm did not tell me the stallion was an EVA shedder - I WOULD SUE THEM ALL THE WAY TO THEIR BANKRUPTCY. My mares live in a herd and the EVA can cause an abortion storm.

'Course naturally, I wouldn't EVER send a mare to an EVA shedder period.

I am breeding my mare to a positive EVA stallion in 2009. I will be sending her to the clinic to be vaccinated and bred. This website gives good info on EVA http://www.equine-reproduction.com/articles/index.shtml. I would hope a stallion owner would have their horse tested and make its status known. The stallion I am breeding to is listed as EVA positive.

Thanks for that link....I loved reading some of the other articles!! Especially liked the one showing the black mare giving birth, in broad daylight no less.

In KY, EVA testing and vaccination of stallions is the LAW.

I agree that there is no reason not to breed to an EVA shedder. There is a very simple fix--VACCINATE.

I realize that there are arguments both pro and con with most folks against it, but this virus can be brought into barns without anyone realizing it until horses start getting sick, and then it is too late. You are foolish to not protect your mare any way you can before they are bred.

[madelyn]

The number one reason NOT to breed to an EVA shedder is that a mare who is vacinated and bred will SHED THE VIRUS to other horses for up to three weeks post breeding. At a breeding farm this can cause an abortion storm. Vaccination protects the mare from getting EVA but she can carry it for three weeks, and give it to all of the horses she comes in contact with.

If you board your horse, it would be downright unethical NOT to tell them the mare was coming back from being bred to an EVA positive stallion - and bringing it smack into their barn. At the very least the mare should be QUARANTINED after breeding.

Since other countries do not permit breeding of EVA shedders, I guess we end up with Europe's unwanted EVA shedder warmbloods.... It is beyond comprehension to me that the US is so tolerant of STD's in stallions while other countries are so strict.

This is true, but I thought the quarantine period was like four weeks. Moot point, however, people have bred and will continue to breed to EVA shedders. I neglected to mention that mares need to be quarantined for a period of time after vaccination and breeding, sorry about that. But whether you like it or not, people will breed to these studs if they like the pedigree, and there really is no reason not to as long as everyone is up front about it, and vaccinations/quarantines are done. It does not stop the foals racing ability.

People wind up with STD's all the time and they keep breeding..

So when can you vaccinate a producing mare??

The article Madelyn provided says not to vaccinate while pregnant but does not address mares with foals..

If i vaccinate just after birth can I still breed on the first full cycle?

Will the vaccine do anything to a nursing foal?/

griff

[madelyn]

griff, it says to the mare will shed the virus for some time after vaccination. I think maybe you could realistically only vaccinate an open mare you could quarantine for that period.

Madelyn

Sounds that way to me also.. I guess that means you take the mare out of production for a year or maybe postpone her covers for a month or two..

I The articel also says you need a booster once a year and I assume thet is after the foal comes and before she is bred..

What do you think will happen to the new born when it's momma is vaccinated?

Sound like you might need to keep the mare open for a full year and only vaccinate the mare after the foal is weaned

Here is the information put out by a DVM in our area. He states that you can vaccinate a pregnant mare up to the last two months of gestation..

You can dispute this with him if you like.

I bred to an EVA shedder last year, (on a foal heat with a colt) and the subsequent foal is fine, the mare was fine, the colt at her side was fine. There was no pregnancy or foaling complications.

Breeders need to perform due diligence of course, but if you educate yourself (read everything you can, talk to every vet you can), AND vaccinate and quarantine after vaccination, you will be okay.

[Derby Lyn]

I was told to quarantine the mare-atleast 15 feet from all other horses-for a period of two weeks after she was vaccinated and/or bred. Since I do not have a place to quarantine my mare, I will be sending her to the vet clinic to do this. As long as she is vaccinated and quarantined, I will have no problems.
There need to be more laws with breeding any animals, but I don't think it is going to happen any time soon. My regular vet knows absolutely nothing about EVA. I bet most of the breeders in MI don't know a thing about it either.

The stallion owner I am dealing with seems to be very responsible and educating all mare owners about EVA prior to breeding to her stallion.

That is good information, thanks for sharing. I am wondering if the colt has been tested recently and what his status was? I just shipped a yearling colt to a sale last week and was surprised that there was an EVA negative test among his paperwork. This colt was not a stallion prospect by any stretch of the imagination due to his pedigree. I supposed if he truly lit the world on fire at the track he could stand regionally but even that is a stretch. I don't know if that is the norm now or not.
